“It is, essentially, about a fear of being consumed. The series’ creative teams are well aware of this and spare little opportunity to viscerally represent the horrifying sight of people being eaten or to cut away at just the right moment to let the viewer’s appalled imagination do the work. The fear of being consumed is of course a natural one – for all human beings’ complex society and technology we are still ultimately meat and bone – and realising it via monsters who look much like large, sexless versions of ourselves is just the icing on the loathsome cake.”
